Four Corners is the only place in the United Status where four state boundaries (Arizona, Colorado, New Mexico, and Utah) come together. It was originally surveyed in 1868 and the first marker was placed there in 1912. The problem is, the survey was wrong. It turns out that the correct intersection is about 2.5 miles east of the marker.
I don’t know why, but I find it strangely humorous that millions of people have visited this monument over nearly 100 years and have taken pictures doing various goofy stunts to cover all 4 states–all to no avail. It was all a lie. (evil laughter)
